THREAD GUIDE.

Application area December 7, 1926. Serial No. 153,155,

This invention relates in general to wind ing machines, and more particularly to an im roved revolving thread guide for use on suc machines, particularly on the unwinding or thread feeding device of the type shown in my Patent No. 1,602,159, dated October 5, 1926.

It is essential that rollers for this use must be light and durable. Heretofore W thread guide rollers for this purpose have been made of fiber, wood, metal or porcelain. The porcelain roller provides the best running surface and the greatestdurabihty but is too heavy for this particular use.

l5 Rollers made of wood or fiber are not sulficiently durable and the thread cuts through them in a relatively short time. Rollers made entirely o'l metal do not provide a running surface as satisfactory as the others W and greater thread breakage results from its use.

It is an object of my invention to provide a built up revolving thread guide which will be'light in construction and which Wlll pro- Q5 vide a suitable running surface, light guiding surfaces, and a suitable bearing for mounting on the compensatmg arm of the unwinding device.

It is an object of my invention to construot my roller of few and simple parts, inexpensively manufactured and assembled, and capable of satisfactory and enduring service. n

@ther objects of my invention will apno pear in the accompanying specification and claims and will be disclosed in the accompanying drawings in which-- Figure l is a perspective of my thread ide mounted on an unwinding device and It in operative position;'

Figure 2 is a longitudinal diametrical section through my device.

Referring now with greater particularity to the drawings it will be seen that my deto vice is comprised as follows:

My revolving thread guide is provided with a bronze bushing 1 for rotatably mounting the same on the bent and 2 of the compensator arm 3 of the unwinding device 4.

to The bushing 1 has barrel shaped enlarged central portion 5 adapted to receive with a very snug fit a orcelain guide 6 providing the running su ace for the thread. A pair of light metal disks 7 formed to provide,

at substantially continuations of the sides of the guide 6, are fitted snugly over the barrel 5 and are pressed over the edges of the uide 6. The bushing 1, as originally lormed, has thin edges 9 which are pressed over to form annular flanges as shown in Figure 2, to hold the parts rigidly in assembled position. i

It will be seen that, by the above structure, I have provided a built up revolving thread guide having a bearing of bronze for mounting the 'same upon the compensator arm, a running surface of porcelain, light metal disks pressed onto the bronze bearing and over the edges of the porcelain holding the same tightly in assembled position and providing means for guiding the thread onto the orcelain running surface.

aving thus described my invention what ll claim is--- 1. For use in winding machines, a revolving-thread guide having a vitreous running surface for the thread, and light metal side plates for guiding the thread onto said running surface carried on said guide.

2. For use in a windin machine, a revolving thread guidecomprlsing a barrel bushing for mounting the same on said machine, an annular grooved guide of vitreous material mounted on said barrel bushing, and light metallic disks mounted on said bushln and formed to guide the thread onto sai vitreous guide carried on said guide.

3. For use in a winding machine, a revolving thread guide comprising a barrel bushing for mounting the same on said machine, an annular grooved guide of vitreous material mounted on said barrel bushing and light metallic disks pressed onto said bushing and said vitreous guide and formed to guide the thread onto said vitreous guide.

' 4. For use in a winding machine, a revolving thread guide comprising a barrel bushing for mounting the same on said machine, an annular grooved guide of vitreous material mounted on said barrel bushing, and light metallic disks pressed onto said bushing and said vitreous guide and formed to guide the thread onto said vitreous guide, said disks having their inner surfaces formed to provide extensions of the sides of the groove of said vitreous guide.

5. For use in a winding machine, a revolving thread ide comprising a metallic bushing, latera ly extending annular flan es thereon intermediate of its ends, an annu ar guide of vitreous material mounted on .said bushing intermediate of the flanges, and a llld Ill

- light metallic disk pressed onto said bushing .central portion and laterally extendin bushing at each end of the annular guide between the face thereof and the adjacent flange. 7. For use in winding machines, a thread guide having a Vitreous runnin surface for the thread, and light metal si e plates for guiding the thread onto said running surface mounted to rotate with said uide.

In testimony whereof I aflix my slgnature.

Y JAMES DANIEL JOYCE.
